We work out the solubility of magnesium chloride.........

#### Explanation:

$\text{Concentration of magnesium chloride}$
$=$ $\frac{285.9 \cdot g}{95.21 \cdot g \cdot m o {l}^{-} 1} \times \frac{1}{0.250 \cdot L}$ $=$ $12.011 \cdot m o l \cdot {L}^{-} 1$.

I do not think that these data are physically reasonable. This is an absurdly concentrated solution, and the question should have been asked using real data.

Clearly the concentration of chloride ion is TWICE that of magnesium.
